Used the above mix to fill small cracks where plywood meets Western Red Cedar on box lid (box is ready to have lid removed/cut off). Two hours later and nicely dried I start sanding& find the natural stain in the WRC dust/glue mix has bled into the ply wood. When attempting to remove the stain (sanding) I have to sand through the top layer of the plywood. Don't know what looks worse,think I'll have to cut the top off the box & rout a new rabbet to house the new plywood top. Anyone had this happen? I will post a pik or two soon,darn it.It's almost finished. Jamesjj777746
